ELECTRICAL CONNECTIONS

All electrical connections should be installed by a qualified (licensed) electrician only. All wiring must comply with the National Electrical Code (NEC) and applicable local codes.

VERIFY THAT ALL POWER CIRCUITS ARE

DE-ENERGIZED AND LOCKED OUT BEFORE

MAKING ELECTRICAL CONNECTIONS.

Voltage Ratings and Power Source Configurations

Before making connections to the unit, verify that the unit model number and nameplate voltage rating are appropriate for connection to the intended power source. See the chart on page 4 for voltage rating applications with typical power source configurations.

Parallel Connection (see Figures on page 5)

EQUIPMENT PERFORMANCE!!

For maximum system performance, the unit must be located as close to the protected circuit as practical to minimize interconnecting wiring length.

To reduce the wiring impedance to surge currents, it is recommended that the phase, neutral (if required), and ground conductors are twisted together and routed in the same raceway (conduit). Avoid any sharp bends in the conductors.

Wire Sizing — With parallel connection, the size of the wiring to the SPD unit is independent of the protected circuit’s ampacity. For suggested wire size refer to individual product sheet.

NEC Article 285-21(B) requires surge suppressor connecting conductors to be at least #14 copper or #12 aluminum.

Overcurrent Protection — The SPD unit conducts practically no current under normal operation and only conducts very short duration transient surge currents.

The following is from the National Electric Code 2002 Edition.

285.21Connection. Where a TVSS is installed, it shall be connected as follows:

(A)Location.

(1)Service Supplied Building or Structure. The transient voltage surge suppressor shall be connected on the load side of a service disconnect overcurrent device required in 230.91.

(2)Feeder Supplied Building or Structure. The transient voltage surge suppressor shall be connected on the load side of the first overcurrent device at the building or structure.

Exception to (1) and (2): Where the TVSS is also listed as a surge arrestor, the connection shall be as permitted by Article 280.

(3)Separately Derived System. The TVSS shall be connected on the load side of the first overcurrent device in a separately derived system.

Disconnect Switch (If Provided) — All SPD units must still be connected to the load side of the main service disconnect, or load side of a protected circuit’s disconnecting means.

Surge Voltage Ratings — To obtain the suppression voltage ratings (SVRs), as obtained by Underwriters Laboratory, Incorporated, in accordance with the Standard for Safety, Transient Voltage Surge Suppressors (TVSS), Standard 1449, Second Edition, dated August 15, 1996, marked on this product, the wire size listed for each product must be utilized to connect the unit to your facilities’ power grid. Connections made with conductors other than the wire size listed may result in different SVRs.

Circuit Ampacity Limitations — Representative samples of these products have been investigated by Underwriters Laboratories, Incorporated to withstand, without exposing live circuits or components at system voltages and fault currents ranging from 14,000 AIC up to 200,000 AIC, as described in the Standard for Safety, Transient Voltage Surge Suppressor (TVSS), Standard 1449, Second Edition, dated August 15, 1996. Verify each products fault current rating on the individual installation pages that follow.
